Policy topic selection

A policy topic is one where someone else, with the same facts but
different priorites, could argue the opposite conclusion.

For example: "how GPS-guided missles work" is not a policy topic. "The
U.S. should not use GPS-guided missiles because doing so would make the
GPS satellites targets vulnerable and the GPS system too valuable for civilian
uses" is a policy topic. Likewise, "Planes using GPS-based guidance
systems should be required to have a non-GPS-based backup, since
the GPS is a military system and GPS-guided missiles may cause the GPS
satellites to become targets" is also a policy topic.

As another example, "how the overuse of antibiotics leads to antibiotic
resistance" is not a policy topic, but "anitibiotic use should be
regulated to reduce antibiotic resistance" or "anitibiotic use should
not be regulated because such regulation would be expensive and cost
lives" are policy topics.

Also, the reasons for your policy must be science-based. "Animals
should not be used for testing cosmetics because it is cruel to the
animals" is not a science-based policy. "Animals should not be used for
testing cosmetics because the approach is less reliable than computer
modelling" is a science-based policy (it is not clear that the this is
true, by the way, but if you have evidence to support it you are
welcome to do this).
